    Gee, I thought I phrased it rather neutrally.....

    So, in Imagine (and R3d) there are essentially alpha mapping functions
    for various textures, correct?  Those alpha maps can be procedural?
    And, from another emailing, there are also procedural gradients
    defining texture, uh, manifestation.

    (Am I getting close?)

    In general, are surfaces object or polygon based in such programs?

    With the current LW surface UI, I wonder how such functionality
    could be implemented.

    Thanks for the info, Eric!  (Man, sure are a LOT of "Eric"s on the
